of fC = 1 (2 π L O C O ) and a quality factor of Q = R L C O L O C O .
CO
Output capacitor, which, in conjunction with LO, demodulates (filters) the switching
waveform into an audio signal. Forms a second order low-pass filter with a cutoff
frequency of fC = 1 (2 π L O C O ) and a quality factor of Q = R L C O L O C O . Use
a high quality film capacitor capable of sustaining the ripple current caused by the
switching outputs.
